I cannot imagine what you mean about the fuel return being cut off.
First check would be for the obvious hoses/wires problems. Make sure
nothing has come loose. Condition of the plugs, etc? Vacuum
readings. If I had to guess, I would say you have a fuel delivery
problem.

Also, don't let anyone rig your car.
